GearWrench 15-Piece Metric Ratcheting Serpentine Belt Tool Set

The GearWrench 3680D is a 15-piece metric ratcheting serpentine belt service set featuring an extended-reach leverage bar, specialized ratcheting wrench, 6-point metric sockets, and crowfoot wrenches designed for 3/8-inch drive belt tensioner assemblies. Engineered for automotive technicians and fleet maintenance mechanics, this professional alloy steel tool set releases spring-loaded tensioner pulleys in cramped engine bays where standard ratchets cannot fit, ensuring fast belt replacements across a broad range of domestic and import vehicles.

Best Used For:

  • Automotive Serpentine Belt Service: Releasing tension on spring-loaded accessory drive pulleys to install new serpentine belts in tight transverse engine bays.
  • Accessing Obstructed Tensioner Fasteners: Engaging low-clearance tensioner bolts using thin-profile crowfoot wrenches (13mm to 15mm) and low-profile metric sockets (13mm to 19mm).
  • Fleet and Commercial Vehicle Maintenance: Servicing accessory drive systems across diverse import and domestic vehicles requiring high-leverage metric socket adapters.

Key Performance & Safety Features

  • Extended Reach Leverage Bar: Provides maximum mechanical advantage to compress heavy spring-loaded belt tensioners with minimal manual effort.
  • Ratcheting Wrench Integration: Connects directly to the extension bar or holds drive adapters for fine arc adjustments in tight clearance areas.
  • 6-Point Socket Geometry: Directs torque to fastener flats to prevent rounding off soft aluminum tensioner bolt heads during high-load compression.
  • Versatile Drive Adapters: Includes 3/8-inch, 1/2-inch, and 3/4-inch drive adapters to accommodate various tensioner pulley configurations.
  • Forged Alloy Steel Construction: Heat-treated alloy steel build handles high rotational torque without bending or flexing under stress.
  • Full Polish Chrome Finish: Premium protective plating offers long-term resistance against jobsite oil, grease, and environmental rust.

  • (1) Special GearWrench Ratcheting Wrench
  • (1) Long Reach Extension Bar
  • (3) Drive Adapters: 3/8 in., 1/2 in., and 3/4 in.
